usually the day I get them. One day I said to my adult daughter, "I'm gonna go put this in the bedroom" (it was a free vibrator for use in the shower) and my husband smiled and said, "I'm gonna help her carry it in."

Sometimes I try them the same day (if they are little and convenient to use) but for larger toys where I will need to warmup with something else, it can be a while till I have that much free time and am in a frisky mood.
